Emergency Vehicle Front Grille Lighting Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional front-end lighting assemblies for vehicles are burdensome to install and often limited to front visibility, which can hinder visibility and safety, especially for emergency vehicles that need to communicate through traffic without risking collisions.
Innovation Solution
A lighting assembly that mounts to the front-end of a vehicle without removing the existing fascia or grille, featuring a frame with light cut-outs and fasteners that allow for side-facing lighting units to enhance visibility and safety by providing both forward and side illumination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional front-end lighting assemblies are installed on the vehicle, then front visibility is improved, but installation becomes burdensome requiring removal of existing fascia or grille
Solution Approach 1:
The lighting assembly is divided into separate modular components including a frame, multiple lighting units, and mounting brackets that can be independently installed. This segmentation allows the lighting system to be installed without removing the entire fascia or grille assembly, reducing installation complexity while maintaining front visibility improvement
Solution Approach 2:
A frame structure acts as an intermediary component between the vehicle's existing fascia and the lighting units. This frame provides mounting points and structural support, enabling lighting installation without direct modification or removal of the original fascia or grille components
2Illumination intensity
If conventional front-end lighting assemblies are used, then front illumination is provided, but side visibility remains limited and may be hindered by vehicle guards
Solution Approach 1:
The lighting assembly extends illumination from a single front-facing dimension to multiple dimensions by incorporating side-facing lighting units. These units project light laterally perpendicular to the front lighting, creating three-dimensional visibility coverage that overcomes the limitations of conventional front-only illumination and vehicle guard obstructions
Solution Approach 2:
Different regions of the lighting assembly provide different illumination characteristics - front lighting units provide forward illumination while side lighting units provide lateral illumination. This local differentiation of lighting function ensures comprehensive visibility coverage in different spatial zones around the vehicle
3Illumination intensity
If lighting assembly requires grille removal for installation, then front lighting can be installed, but installation time and labor increase significantly
Solution Approach 1:
The frame and mounting brackets are pre-configured with attachment points and alignment features before installation. This preliminary preparation allows the lighting units to be quickly mounted to the frame and then the entire assembly to be installed on the vehicle without time-consuming grille removal procedures
Solution Approach 2:
The lighting system is segmented into modular components that can be pre-assembled and tested separately, then quickly installed as a complete unit. This modular segmentation eliminates the need for sequential installation steps involving grille removal and reduces overall installation time
